Ok so I’m kinda new to the deleted Cummins world so over look anything I mention that sounds goofy LOL... so anyway I just recently deleted my 18 RAM and my fuel economy was went to crap for some reason and my boost gauge on the dash shows me pulling more psi of boost now in places that I never boosted like that before (mainly interstate driving).
I’m not hard on the truck by no means it’s my daily driver but anyway I’m just curious as to what’s making me use more fuel and what’s causing me to build boost more now and all I installed was a 5” turbo back with muffler and s&b cold air intake with a RaceME Ultra tuner.
Any help will be greatly appreciated also I usually just run it in the stock tune with deletes.
